Is it possible that all of your neighbors in your building have their heater on? This is what happened to me in a building in NYC. It would actually get so warm in the winter I would have to crack the window open or I would get a nose bleed.

As someone who also lives in Toronto: most things being built now are giant class towers. Now, glass sucks at insulation (even triple glaze), but—depending on the coatings—it lets in a lot of sun light and with that potentially heat. While in a perfect world there would be no / minimal exchange between the inside of the structure and the outside,† being too warm may be better than being too cold, as I'm guessing that it's easier to throw away the 'free' heat of the sun away than introducing it in winter. Certainly heat pumps can go either way, but I figure that it's easier to dump it. † The entire point of "buildings" are to be environmental separators after all.

  There is a courthouse in Phoenix, Arizona, USA built predominately with glass. Summer days there are in the 40s. It boggles my mind.

>or I would get a nose bleed. Are nose bleeds associated with high temperatures?

  Yes. I'm not completely sure the mechanism, but I attended elementary school in a warm climate, at a school in which the hallways were exterior and only classrooms air conditioned. I reliably got nosebleeds on the three or four hottest days of th year in line for class.

  I think dry air is a larger driver, but that often comes with excessive interior temperatures.

  Heating plus air leaks results in dry air. As you heat some air the relative humidity drops. If your room is not leaky, the relatively humidity will rise as it cools back off, but if you're constantly leaking air your indoor humidity will approach that of the outside air raised to the indoor temp. This is why energy recovery ventilators exist-- to exchange outside air without losing or gaining as much relative humidity change.
